Hardware Setup

Board Setup

Below is the minimum setup required for the AM3517 EVM:

• Null-modem serial cable connected to the EVM (UART 3) and the development PC
• Ethernet cross over cable connected to the EVM and the development PC (or both EVM and PC connected to a switch via standard Ethernet cables)
• 5V power supply connected to the EVM

USB Hardware

USB client devices such a mouse, keyboard or flash drive can be attached directly to the EVM via the Experimenter board USB Host or USB OTG port.

To attach client devices via the USB Host port you will require:

• USB Powered Hub.

To attach client devices via the USB OTG high speed port you will require:

• USB type A socket to micro-A plug (the micro-A plug has the ID pin grounded).

To attach the EVM to a PC (for ActiveSync for example) the OTG port can be used with the following cable:

• USB A plug to micro-B plug

Suitable cables are supplied with the EVM.

Audio Hardware

To use the audio features in the BSP you will require the following hardware connected to the 3.5mm audio jacks:

• Line in source – LINE IN CODEC 1 (J12)

• Microphone in source – MIC IN CODEC 1 (J13)

• Headphones / speakers – LINE OUT CODEC 1 (J9)

• Headphones / speakers – LINE OUT CODEC 2 (J10)

By default the audio driver will use LINE IN Codec 1 and LINE OUT Codec 1. This can be changed using the wavmixer.exe tool.

Note that Codec 2 does not have a "Line In" connector wired up.

SD/MMC Cards

The SD card driver in the BSP supports use of SD cards (including high capacity cards) and MMC cards (including MMCplus 8bit cards).

Note that the data lines required for full 8-bit transmissions are not connect. Cards that support 8-bit will be mounted and used as 4-bit.

Display Hardware

The display driver supports the LCD panel on the AM35x eXperimenter board. The display driver supports the following features:

• Windows GDI
• DirectDraw
• Hardware accelerated rotation using VRFB

The display driver supports the following panels and resolutions:

• Onboard LCD display - 480x272@60 Hz
• External DVI display – 640x480@60 Hz
• External DVI display – 640x480@72 Hz
• External DVI display – 800x480@60 Hz
• External DVI display – 800x600@60 Hz
• External DVI display – 800x600@56 Hz
• External DVI display – 1024x768@60 Hz
• External DVI display – 1280x720@60 Hz

The panel/resolution to use is configurable through EBOOT’s menu item named "Select Display Resolution".

Video Input Hardware

The video input driver supports right now only composite video (via TVP5146). Here are the steps needed in order to enable and use video input.

Before booting the board, make sure "user switches" on the application board are configured as this: 1,2: ON ; 3,4: Don’t care.

In your OSDesign, make sure VRFB driver is not selected.

Connect the video player to the composite video input on the application board (currently, this is the only one supported).

Building the BSP

Tools Setup

Connect the development PC to the EVM using the serial cable and configure your chosen serial terminal application for 115200 baud, 8 data bits, 1 stop bit, no parity:

IMPORTANT: If you have other development tools installed on your PC check that they have not defined environment variables that may conflict with VS2005. For example, check if MAKEFLAGS or INCLUDES have been defined and un-define them before starting VS2005.

BSP Source Code Installation (ToDo: Update after install jammer is done)

Extract the BSP source code from the release installation file. Move the OS designs and BSP platform files into the relevant locations for Windows Embedded CE 6.0:

Move extracted folder: BSP\AM35x_BSP

To: C:\WINCE600\PLATFORM\

Move extracted folder: BSP\COMMON\SRC\SOC\COMMON_TI_V1

To: C:\WINCE600\PLATFORM\COMMON\SRC\SOC\

Move extracted folder: OSDesigns\AM35x_OSDesign

To: C:\WINCE600\OSDesigns\

Move extracted folder: PowerVR\PowerVR

To: C:\WINCE600\PUBLIC\

To: C:\WINCE600\PUBLIC\

Move extracted folder: 3rdParty\dvsdk_1_10_00_00

To: C:\WINCE600\3rdParty\

BSP Build Notes

Before building and running an OS design the following is a configuration change you may wish to make:

• Console access – Windows CE does not provide a shell on the UART but you can telnet to the target to get a text console. See the Telnet and FTP section below for details on enabling telnet support.

Building the OS Design

The BSP comes with the following OS Design:

• AM35x_OSDesign – Fully featured design including the Silverlight demos, Windows Media Player and Internet Explorer (see the Demo OS Design section below for more details).

In Visual Studio 2005, open the solution file for the OS Design you wish to build. For example: C:\WINCE600\OSDesigns\AM35x_OSDesign\AM35x_OSDesign.sln

Select a release build by selecting menu option Build -> Configuration Manager and selecting AM35x_ARMV4I Release as the Active solution configuration:

To build the OS design select menu option Build -> Rebuild Solution.

This will build an EBOOT boot-loader image and a CE 6.0 OS image.

Running OS Designs

This section describes how to boot using the SD Card on the EVM. For details of booting from NAND, or flashing the EBOOT over Ethernet, or Serial see the User Guide.

Booting AM3517 from SD Card.

The EVM is capable of booting the BSP from a correctly formatted, programmed and inserted SD memory card. Use the TI SDCard boot utility provided in this release to do so. Select MLO and then EBOOTSD.nb0 to obtain a bootable SD Card.

Use the following switch settings on the EVM to boot from SD Card:

SW 7 Switch Position
1	2	3	4	5	6	7	8
ON	OFF.	OFF	ON	OFF	OFF	OFF	OFF

Configuring EBOOT

Once EBOOT is flashed and running you can configure the bootloader settings. Use your serial terminal application (115200 baud, 8bit, no parity, 1stop) to access the EBOOT menus by pressing SPACE when EBOOT is booting. SD Eboot is preconfigured to load NK.bin from the SD Card, so no configuration changes are needed. More information on loading NK from another source can be found in the User Guide.

Booting the Kernel

To boot from SD Card, make sure NK.bin exists on the SD Card.

In the EBOOT menu press [0] to load WinCE.

Customizing an OS Design

CE 6.0 Catalog

OS designs are customized by selecting components from the CE 6.0 catalog. The catalog can be seen by selecting the Catalog Items View tab in VS2005, or selecting View -> Other Windows -> Catalog Items View:

The catalog is divided into the following sections:

• BSP – Contains reference BSPs shipped with CE 6.0. You do not generally need to select anything in this section.

• Core OS – Contains the standard CE 6.0 components. The CE 6.0 features you wish to use in your OS design are selected from this section.

• Device Drivers – Contains drivers for some commonly used hardware components.

• Third Party – Contains BSPs not shipped with CE 6.0, such as the AM35x BSP.

The sections below describe which catalog components need selecting to support particular features or functionality of the AM3517 EVM.

OS Build Caveats

When Core OS or Device Drivers catalog selections are changed in an OS design you need to perform a clean and full rebuild. This can be done using the build menu in VS2005 by select Clean Solution followed by Rebuild Solution. This should ensure that the correct image is built.

If you change just AM35x BSP catalog selections (under Third Party \ BSP \ AM35x_BSP) it is usually possible to rebuild just the BSP (menu option Build -> Advanced Build Commands -> Rebuild Current BSP and Subprojects). Be warned though that this does not always rebuild every part of the BSP that is affected by the catalog change. If you see unexpected build or run time issues then perform a clean and full rebuild as described above.

BSP Component Conflicts

Due to the extensive SOC pin multiplexing and the EVM design there are some BSP component combinations that are not supported. When customizing an OS design the following component conflicts should be observed:

• The USB Host Port 2 (App board)requires that the Display driverbe disabled and NULL (Stub)display driver be enabled (NULL (Stub)can be found under Device Drivers \ Display).

KITL Configuration

KITL over Ethernet is supported by the BSP. Enabling KITL in an OS design enables development tools such as the

Target Control and the Kernel Debugger to be used. KITL and the kernel debugger are enabled via the project properties:

Project -> Properties -> Configuration Properties -> Build Options

KITL and the Kernel Debugger can be enabled or disabled for both Debug and Release builds.

Rebuild the BSP after changing build options.

*Note: to use KITL image, you must download image over Ethernet, see User Guide for detailed instructions.

NDIS Ethernet Configuration

The TCP/IP settings for the driver are configured in the EBOOT menu. Optionally you may edit the following registry files for the EMAC on the Experimenter board, or the SMSC9118 on the Application board:

C:\WINCE600\PLATFORM\AM35x_BSP\SRC\DRIVERS\EMAC\omap_emac.reg

or

C:\WINCE600\PLATFORM\AM35x_BSP\SRC\DRIVERS\SMSC9118\smsc9118.reg

Find the TcpIp section:

[HKEY_LOCAL_MACHINE\Comm\EMAC1\Parms\TcpIp]

or

[HKEY_LOCAL_MACHINE\Comm\SMSC91181\Parms\TcpIp]

Change the IP settings appropriately for your LAN.

Demonstration OS Design

Overview

A demonstration OS Design (AM35x_OSDesign) is included with the BSP. This OS design includes the following CE 6.0 components:

• Silverlight sample application
• Windows Media Player
• Software audio codecs for WMA and MP3
• Software video codecs for WMV/MPEG-4 and MPEG-1
• Streaming media support
• Internet Explorer 6.0 Sample Browser

Notes:

1. Internet Explorer 6.0 is a heavyweight application so expect it to run quite slowly.
   
2. The software video codecs used by Windows Media Player max out the CPU when running so expect playback to be slow and frames to be skipped.
   

Standalone Boot

The EVM can be configured to boot the OS design standalone from an SD/MMC card. Perform a Release build of the OS design, as described in the sections above. The OS image can then be found in the following location:

C:\WINCE600\OSDesigns\AM35x_OSDesign\AM35x_OSDesign\RelDir\AM35x_BSP_ARMV4I_Release

Write the OS image to an SD/MMC card using a PC card reader:

1. Format the SD/MMC card with a FAT32 file system using the TI SDCard boot utility provided in the release.
2. Copy MLO, ebootsd.nb0, and NK.bin to the SD/MMC card.

   
   

Configure EBOOT to boot the image from SD card:

1. Insert the SD/MMC card into the SD slot on the EVM.

2. Use the following switch settings on the EVM to boot from SD Card

SW7 Switch Position
1	2	3	4	5	6	7	8
ON	OFF	OFF	ON	OFF	OFF	OFF	OFF

3. Power on or reset the EVM. Use your serial terminal application to access the EBOOT menus by pressing SPACE when EBOOT is booting.

4. Boot Device is set to SD Card by default.

5. Exit the menus to boot the CE image from the SD/MMC card using option 0

6. Wait while image is read and booted.
